Cuif, 1976: 159
Thamnastraea norica Frech, 1890: 63; Monotypy Cuif, 1976: 159
Type Specimen: Lectotype; BSPG AS XII 7; Verified; Dry Preserved
Type Locality: Fischerwiese, Northern Calcareous Alps. Zlambach Beds, Rhaetian, Late Triassic
From the specimens figured in Frech, 1890: pl.17, fig. 1-6, the specimen figured in pl.17, fig.3 was chosen in Roniewicz 1989:62 as the lectotype. Paralectotypes: BSPG AS XII 121-124.
Emended by Roniewicz 1989: Thamnasterioid; calices in meandroid series. Distal and internal septal edges smooth. Lateral septal stereome organized into fascicles of fibres, with axes rarily observed; lateral septal micromorphology granular. Endotheca abundant, small-vesicular.
Original description of Cuif 1976: 154, and figures: pl.17, fig.2,3, were completed with additional description and illustrations in Roniewicz 1989:62, pl.15, fig. 3,4,6.
In thamnasterioid type of connections of corallites in the colony, it is similar to Campesteria Caruthers and Stanley, 2008, and Margarogyra Roniewicz, 2010. From the former it differs in reimaniphylliid type of the microstructure, with a midseptal zone containing small trabeculae, from the latter, with which it is nearer systematically, it differs in having lateral septal stereome poorly orgnized, with fascicles of fibers rarily presenting axes.
- Southern Europe; Late Triassic
